Home Security - Hardening the target
Joe,
Rule #1 - Don't go looking for an intruder. You might just find him.
Rule #2 - You probably don't know how many or where. Stay put. Call cops.
Rule #3 - Lights & noise are a thief's worst enemy when he's trying to get in.
Don't overlook getting Dad to spring for a 20 gauge version of the shotgun. It should be short (18-20" barrel). Sometimes a used one turns up cheap.
Will they let you take up archery?
Harden the target
I can't list everything here, but here are some things you can do with just a few dollars.
Windows
For sash windows or horizontally sliding windows go to a hardware store and purchase some 3/8" or 1/2" aluminum "U" channel stock -- normally 4ft to 6ft long. Cut the stock to a length that allows windows to be open only 2" or less for ventilation. Place the channel stock in the window track of sliding windows to prevent them from opening. For sash windows you'll have to devise a way of retaining them in place but allow the window to open when they are removed. The "U" channel also works for sliding glass doors if they slide on the
inside of the house (as they should).
For louvered glass windows, such as some bathroom windows, remove each pane/plate of glass and tack a short bead of silicone sealant in the track, then slide the pane back in place. Let dry, remove excess with a razor or utility knife.
Doors
For doors, replace every wood screw with a 1 1/2" or longer wood screw. This includes hinges, strike plates and the chain latch if you have one. Add one of the brass door knob reinforcement plates around the door knob to prevent the door from splitting if kicked. Add a deadbolt and use longer screws on its strike plate. Don't forget to reinforce doors from the garage & back yard too!
For the front door, you might consider making a strike-stop as pictured in the attachment. It's not to scale but gives you an idea if there is a wall near the door. Should cost under $20 to make yourself. The retaining pin has to be into a solid floor and will require drilling -- line the hole with a brass tube or steel tubing crimped at the bottom end. Attach pin to the stop with a cord. An empty soda can with 5 marbles hanging off the door knob provides a crude alarm.
